Space colonization is a wonderful opportunity to create unique civilizations, each pursuing their own destiny. Where does your sadistic desire to control the future of entire mankind come from?

Ability to choose different paths is far more appealing than suffering under some inescapable dystopian global diktat you have in mind. So yes, we should extend tribal thinking to space. Platitudes like "we are single human race" are as meaningful as saying we are all life.

Sure is good that "tribal thinking" has never led to dystopias of any sort!</sarcasm>

Also: how exactly is OP being sadistic, or planning a "global diktat"? Those are very strong accusations.
